Usability, accessibility and security are some of the
properties that constitute the quality of a website. High
level of quality can only be achieved if proper
organization, work processes and tools for usability and
accessibility are deployed. Open research issues I'm working
on include proper understanding of effectiveness of
automatic tools for testing accessibility, appropriate
merging of automatic and manual assessment methods for
accessibility and usability, how to measure
accessibility.

More detailed descriptions of projects I'm working on
(Barrier Walkthrough method, accessibility metrics,
usability of text-only pages) can be found in
the projects page.
